Ensure that the l10n control files are staying in their state, [browser|mobile]/locales/all-locales, shipped-locales, maemo-locales.

notably, on desktop, certain locales (eg: csb, mn, sw - but check for current status) should not be in shipped-locales even though they are being built in beta. Confirm with Axel if any new locales that were previously beta-only are now ready for release shipping.

# Starting with 10.0, ensure mobile/{android,xul}/config/mozconfigs/android/* have branding set to release on mozilla-release <- no longer needed
